Application filed February 18, 1919. Serial No. 277,872.

T 0 aZZ whom iii may concern:

Be it known that I, MAYME JEFFERSON PEP ARD, a citizenof the oUnitedgStates residing at Minneapolis, in the county ofI-Iennepin and State of Minnesota, have invented a new and useful Improvement in Machines for Forming Hair-Curlers, of which the following is a specification;

The particular object of this invention is the production of an apparatusowhich will quickly and economically produce the wire bodies of hair curlers of that particular type set forth in Patent No. 1,217,816 granted to me on the 27th day of February, 1917.

In the accompanying drawing forming part of this specification, Figure 1 is a plan of my invention; Fig. 2 is a section .of a detail taken on the line 2.2 of Fig. 1, the hair curler being omitted; Fig.. 3 is a side elevation of a detail showing the revoluble forming member; Fig. 4:. is a perspective view of a detail showingthe guard; Fig. 5 is' a plan of a detail showing a portion of the revoluble forming member, and Fig. 6 is aiplan of one .of my improved hair curlers, the wire body of which is adapted to be formed by invention.

In the drawing, let "A indicate a base plate which may be of any suitable construction, to form a support. This base plate has a shallow, circular opening 10 in its surface and a vertical passage 11 concentric with, said opening, extending downwardly through the plate. ,Arranged in the opening 10 15. a revoluble formingtool support in the form of a disk 12 which is free to turn in the Openingand carries uponfitsfsurface a form.- ing t'o0l.13 which is. secured between two flanges 14, on the disk by the pin 15.. .The forming tool support is turned by a handle 16 radiating outwardly therefrom and is adapted to move from the full. line position shown in Fig. 1 into the broken line position in itsrope'ration. The support A is formed with a back rest 17 which has .a vertical wall 18 radiating from the central portion of the disk 12. My improved hair curler is'adapte'd'to'gbe'formed out of a piece of wire 19 of suitable length and in its formation is bent between its ends into the form of a crotch 20 at one end and an eyelet 21, at its other end, the sides 22 and 23 of the crotch tapering or converging to the eyelet end of the device. The two extremities of the wire thus formed meet adjoining the eyelet below a clip 24twhich is afterward secured around the sides of the device, after a rubber band 25 has been inserted through the eyelet.

The. straight piece of wire to be formed intothe hair curler is laid along the wall 18 with one of its ends extending across the surface of the disk 12, the distance and position being regulated by a guard 26 which is fastened to the back support 17 in regulated position by the screws 27 passing through slots 28 The guard 26 is in the form of a platehaving an outer downturned. shoulder 29 on its outer end which is curved to correspondwith the periphery of the, disk above the surface thereof, and againstwhich the end ofthepiece of wire 19 is placed. An anvil member 31 is secured through the surfaceof thesupport A with one ofits sides c'loselyadjoining, spaced from and extending parallel to the shoulder 18 for a short distance to produce-a channel in which the body of the wire 19 is laid, when it is adjusted inthe device torbe formed. When in this position the forming tool 13 and its handle are in the full line position illus trated in Fig. 1, said forming tool being provided, with an ,mzcrhanging shoulder 32 which projects over the. wire to hold the latter in position, A mandrel 33 in the formv of a, thrust,- shaft or pin projects through, and is slidably mountedin the opening 11 and projects up through and normally,v the mandrel is in uppermost positionl. asillustrated' in. Fig. 2 but may be withdrawn below the surface of the disk and against the'tension of the spring 36. The lower end of the mandrel has an eyelet 37' to which is attached a link 38, said link being in turn pivotally secured to a foot lever .39 which is fulcrumed on the support &0 andmay be tilted down by placing the foot on its outer end to withdraw the mandrel from above the surface of the disk, after each forming cycle of operation of the machine.

After the strip has been placed in the machine in readiness to be formed, the lever 16 is swung from full line position into the broken line position illustrated in Fig. 1

whereupon the forming tool 13 engages the lower end of the wire and wraps it around the mandrel, bending it into the full line position shown in Fig. l. The upper end of the strip of wire is bent over the anvil 31 by swinging lever members 41 and 42 into the full line position shown in Fig. 1. The lever member 42 is pivoted at 43 on the support A and has a knife member 44 formed on its work end which swings into a curved recess'45 which is formed on the outer end of the anvil thus imparting a crotch formation to the strip of wire.- The lever 41 is pivoted at 46 on the work end of the lever 42 and is formed with a fiat side 47 which is adapted to engage the strip of wire and fold it against the anvil to produce the side 22 corresponding with the side 23 of the crotch, with the free end of the wire meeting the lOWer upturned end which is formed around the mandrel 33. In folding the wire to form the crotch 20 and side 22, first the lever 42 is swung down on its pivot 43 into the full line position shown in Fig. 1 and then the lever 41 is swung inwardly on its pivot 46 into the full line position. Thus, the hair curler is formed in readiness to receive the elastic band in the eyelet 21 after which the clip 24 is secured around the sides and over the joint to complete the curler. After 7 the curler has been formed and previous to securing the resilient member through the be lifted off of the device in readiness foreyelet and the clip around the sides, the levers 41 and 42 are swung back and the mandrel 33 withdrawn by pressing downwardly upon the lever 39 leaving the curler free to a new strip, of wire to be placed in and formed by my invention.

In accordance with the patent statutes I have described the principles of operation of my invention together with the apparatus which I now consider to be the best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described my invention; what I claim is new and desire to secure by Letters Patent is:

l. A machine for forming a hair curler having a crotch at one end, an eyelet at the other end and a pair of sides converging from said crotch to said eyelet, comprising, in combination, a supporting base, means for holding a strip of wire to be bent into the into the shape 0 'ment to bend the free portion of the wire into said recess to form a crotch and over said anvil to complete the opposite side of the curler.

2. A machine for forming a hair curler having a crotch at one end, an eyelet at the other end and a pair of sides converging from said crotch to said eyelet, comprising, in combination a supporting base having means for holding astrip of wire to be shaped into said curler, a recedable mandrel mounted in said base, a tool cooperating with said mandrel for bendinga portion of the wire about said mandrel when the latter is in normal position, into the form of an eyelet, an anvil having a crotch-forming recess and a movable tool cooperating with said anvil and adapted by its movement to bend the median portion of the wire into said recess to form the crotch and the remaining free portion of the wire over said anvil to complete the pair of converging sides of the curler.

3. A machine for forming a hair curler having a crotch at one end, an eyelet at the other end and a pair of sides converging from said crotch to said eyelet, comprising, in combination, a supporting base having means for hol 'ng a strip of wire to be bent tool cooperating with said mandrel for bending a portion of thewire held by the base into the shape of an eyelet while a remaining portion of the wire is held in the form of one side of the curler, an anvil on said base having a crotch-forming recess and a compound tool cooperating with said anvil, having one movable member mounted upon said base and adapted to bend a portion ofthe wire into said recess to form the crotch and another movable member mounted upon the first movable member adapted by its movement to cooperate with said anvil in bending the wire and completing the opposite side of the curler.

In testimony whereof I have signed my name to this specification in. the presence of two subscribing witnesses.
